Prostate MRI has become an increasingly frequent examination faced in daily radiological practice and is mainly conducted for the detection, active surveillance and staging of prostate cancer. This approach is an example of how to create a radiological report of a prostate MRI with consideration of different imaging features and relevant clinical data.

Recommendations have been given in the Prostate Imaging-Reporting and Data System document of which the latest version has been published by an internationally representative group involving the American College of Radiology , European Society of Urogenital Radiology , and AdMeTech Foundation 1,2.

The approach below takes recommendations from those documents and those of other societies as well as personal experiences into consideration 1-4.

Pitfalls Related To Clinical Indications

These pitfalls are related both to the anatomy of the prostate and to certain benign conditions of the gland, which can mimic the presence of cancer. The typical appearance of PCa in the PZ is a focal hypointense area on T2-WI however, other benign conditions, such as prostatitis, fibro-muscular bands and post-biopsy haemorrhage can mimic this signal change, leading to potential misdiagnoses.

Pitfalls Related To Technical And Physiological Artefacts

The use of an endorectal coil in addition to the surface coil improves the signal-to-noise ratio and the spatial resolution both at 1.5 and 3 T. On the contrary, patient or bowel movements during image acquisition may cause repetitive circular artefacts along the boundaries of the endorectal coil. These artefacts can be minimised by rectal emptying and by the administration of a spasmolytic drug prior to the examination.

According to PI-RADS v. 2, an area of homogeneous low-signal intensity on T2-WI in the PZ, showing restricted diffusion on DWI and focal enhancement can be scored as 4/5, suggesting the presence of clinically significant PCa. However, the use of a single surface coil could erroneously suggest extracapsular extension because of the lower resolution. In this case, the application of PI-RADS v. 2 together with the use of the endorectal coil could help to rule out capsular involvement , thanks to the increased resolution.

The white arrows show an area mimicking restricted diffusion on DWI and focal enhancement on DCE imaging in the left peripheral zone, very close to the prostatic capsule and adjacent to the endorectal coil surface. This finding could be erroneously interpreted as a lesion, but the axial T2-weighted image does not show this artefact, and therefore prostate cancer can be ruled out. Red arrows show the coil surface

    Recommended Reading: Steps To Prevent Prostate Cancer

    Mri Of The Prostate: A Practical Approach

    Although prostate cancer is the second leading cause of cancer death in men in the USA, it can be treated successfully if detected early. Disease management has gradually changed to a paradigm that relies on close monitoring through active surveillance in select patients, as well as ongoing refinements in treatment interventions, including minimally invasive procedures. This has resulted in a critical need for a more exacting methodology for performing targeted biopsies, assessing risk levels, and devising treatment strategies. Prostate MRI has emerged as the most precise, state-of-the-art imaging modality for prostate cancer diagnosis and management, thereby creating an immediate demand for radiologists to become proficient in its use.

    Conceived and edited by a leading authority, with contributions from renowned experts in the field, MRI of the Prostate: A Practical Approach is the first book to tackle this important topic. It provides an overview of the fundamentals of prostate MRI acquisition, interpretation, and reporting. Readers will benefit from a wide range of insightful perspectives gleaned from years of hands-on experience.

    Key Highlights

    Mri Of The Prostate: A Practical Approach Reviewed By Tim Lane

    The MRI is a non-negotiable part of prostate cancer diagnosis and management. As a result, this book is an essential. This nicely illustrated and well written account covers aspects ranging from MRI protocols, through Prostate Imaging Reporting and Data System scoring to more recent innovations in the field of positron emission tomographymagnetic resonance imaging scanning.

    All of the chapters are well placed for the urological surgeon . Even in those chapters where the confidant urologist might claim a comparative knowledge to his radiology colleagues there are surprises. PI-RADS scoring in transition zone lesions was a particularly enlightening aspect of the chapter on reporting. Post-treatment follow-up and assessment using MRI covered new ground for me as did the degree to which MRI scanning has become pivotal in active surveillance protocols. The extent to which an MRI of the prostate currently dictates surgical planning is perhaps the best covered of the sections . At a time when so much depends on the MRI imaging of the prostate this text will allow the urological surgeon to discuss on equal terms some of the decisions that are based on imaging alone and as such contribute more directly to the imaging-led decision making progress.
